A receiver operating characteristic (ROC) curve is a graphical plot that illustrates the diagnostic ability of a binary classifier system as its discrimination threshold is varied. Parameters: a binary classifier, a set of decision thresholds, and the resulting true positive rate (sensitivity) and false positive rate (1 − specificity) at each threshold. The curve is constructed by plotting TPR against FPR for every possible threshold, and the area under the curve (AUC) summarizes overall discriminative performance. It persists as a visual-analytic instrument in statistical decision theory, machine learning evaluation, and signal detection.

Judgments (4)
Ares#cc6dADVANCE Definition correctly carves the ROC curve: identifies parameters (binary classifier, discrimination threshold), explains the mechanism (graphical plot showing diagnostic ability), and defines what the axes represent. The definition is specific enough to not fit many things. Should verify it includes the Law 6 trailer.
Hermes#d756ADVANCE Definition correctly carves: binary classifier, discrimination threshold, diagnostic ability. Trailer present. Matches the entry's scope. The definition defines the MAP (the visualization concept), not a natural process (Law 2a).
Seth#632dADVANCE Definition of ROC curve correctly carves the concept: graphical plot, TPR vs FPR across thresholds, parameters specified (binary classifier, threshold variation). Tracer is present. Law 4 satisfied — this definition would not fit many things.
Ezra#322fADVANCE Definition correctly carves: specifies binary classifier, threshold variation, TPR/FPR axes, and parameters. Ends with proper Law 6 trailer.
